In a particular region, there is a uniform magnetic field with a magnitude of 2.00 T. You take a particle with a charge of +6.00
expeople1 [14]

Answer:

a) 1.68 N b) 0 c) 14.5º

Explanation:

a)

  • The force on a charge moving in a magnetic field, is a vector perpendicular to the plane defined by the velocity of the charge and the magnetic field.
  • The magnitude of the force F is given by the following expression:

       F = q*v*B*sin\theta (1)

  • where q= magnitude of the charge of the particle, v=velocity of the particle, B= magnitude of the magnetic field, and θ= angle between v and B.
  • Replacing by the known values in (1) we have:

       F = q*v*B*sin\theta (1) = 6.00e-6C*1.40e5m/s*2T*sin\theta=\\ \\ F= 1.68N*sin\theta

  • The maximum possible value of F happens when sin θ =1
  • This means that v and B are perpendicular each other (in the same plane)
  • So, Fmax = 1.68 N

b)

  • If the maximum possible value of F happens when sin θ = 1, the minimum possible is when sin θ = 0.
  • In this case, when v  and B are parallel each other, the force is just 0.

c)

  • If the force is 0.25 of the maximum possible, (which is when sin θ =1), this means that sin θ = 0.25, as it can be seen below:

       F_{\theta} = q*v*B*sin \theta = 0.25*Fmax\\ F_{\theta} = q*v*B*sin\theta= 0.25 (q*v*B*sin 90) \\ sin \theta = 0.25

       \theta = sin^{-1} (0.25) =14.5 deg

  • The angle between the velocity v and the magnetic field B is 14.5º.

A body of volume 2000 cm3 has a mass 4 kg. Find the density of the body. Will the body sink or float in water, if the density of
Brums [2.3K]

Answer:

2 g/cm^3, it will sink

Explanation:

The density of an object is given by

d=\frac{m}{V}

where

m is the mass of the object

V is its volume

For the body in the problem, we have

m = 4 kg = 4000 g

V=2000 cm^3

Therefore, its density is

d=\frac{4000}{2000}=2 g/cm^3

And the object will sink in water, because its density is larger than that of water, which is 1 g/cm^3. (an object sinks when its density is larger than that of water, otherwise it floats).
